As of September 6, you have 24 days left to customize an ice cream bar at Magnum's pop-up store in New York City.

The process is simple. First, pick between a chocolate or vanilla Magnum ice cream bar. Then, pick three out of 20 different toppings which range from the whimsical (e.g., mini mint chocolate chips) to the extravagant (e.g., edible rose petals). Finally, choose what type of chocolate you want to dip your bar in: white, milk, or dark Belgian chocolate.

According to Magnum, there are over 200,000 possible combinations, so you can enjoy a completely different ice cream bar each time you visit the pop-up.
